Evening: I am tasked with getting the"old fella
down the road" Case 444 back in service, so far
I have it running, mower deck fixed and hyd
system good. What i am having trouble with is
that it will not charge, had a shop re-build
the starter/gen, did the armature/field test
shown on youtube also.
The battery reads 12.13 volts not running and
12.03 when running, disconnecting field wire
makes no change.
engine speed makes no difference, belt is tight
tried a new regulator[ 3 terminal] and no
difference, does it need an original 4 terminal
regulator? rear terminal is connected to
battery neg on the original.
Charge indicator stays on, and if ARM/BAT
terminals are shorted, it draws a spark and
current enough to blow the fuse from the
battery to the BAT terminal.
Also I found that the coil power is only there
when the key switch is in the "lights"
position, when turned to start, the 12 volts is
switched off, so I have to get it rolling in
the start position on the key and let it turn
back to lights and catch the engine as it is
rolling.
Is this how they were built, or has someone
changed the switch?, I checked the contacts as
to what was closed when and it is as described.
Sorry for length but tks if you have an idea.
